Solved What USB-to-RS-232 adapter will work with Windows 8.1?

Virtually all the USB-to-RS-232 (9-pin) adapters for sale on eBay have a disclaimer, which states that they will not work with Windows 7 and 8 64-bit systems, even with the software drivers supplied. Does anyone know of a USB-to-RS-232 adapter that will work on a system running Windows 8.1, 64-bit?Thanks.

Thanks, Riider. We're talking about a laptop here, so RS-232 adapter card is not an option. I'm running a program called CWCOM, which allows users to send and receive Morse code over the Internet. The only option for connecting a telegraph key is via RS-232, which of course this modern laptop does not have. So, I'm trying to create one via a USB-RS-232 adapter.
